Nursing Elites

1. If Ms. Barrett's distance vision is 20/30, which of the following statements is true?

• A. The client can read from 20' what a person with normal vision can read at 30'.
• B. The client can read from 30' what a person with normal vision can read at 20'.
• C. The client can read the entire chart from 30'.
• D. The client can read the chart from 20' with the left eye and from 30' with the right eye.

Correct answer: A

Rationale: When Ms. Barrett's distance vision is measured as 20/30, it means that she can read from 20 feet away what a person with normal vision can read at 30 feet. The numerator (20) represents the distance in feet between the chart and the client, while the denominator (30) indicates the distance at which a normal eye can read the chart. In this case, Ms. Barrett's vision is slightly worse than normal, as she needs to be closer to the chart to read it clearly. Therefore, choice A is correct. Choices B, C, and D are incorrect: Choice B reverses the distances, Choice C assumes the client can read the entire chart from 30 feet, and Choice D introduces information not related to the 20/30 measurement.

2. While a client is on total parenteral nutrition, which of the following values should the nurse monitor closely?

• A. calcium
• B. magnesium
• C. glucose
• D. cholesterol

Correct answer: C

Rationale: Glucose should be monitored closely when a client is on total parenteral nutrition due to the high glucose concentration in the solutions. Monitoring glucose levels is crucial to prevent complications such as hyperglycemia or hypoglycemia. Calcium and magnesium are usually monitored to assess electrolyte imbalances, while cholesterol levels are not directly impacted by total parenteral nutrition. Therefore, choices A, B, and D are not the primary values that need close monitoring during total parenteral nutrition.

3. A nurse calculates a newborn infant's Apgar score 1 minute after birth and determines that the score is 6. What is the most appropriate action for the nurse to take?

• A. Initiate cardiopulmonary resuscitation
• B. Gently stimulate the infant by rubbing his back while administering oxygen
• C. Recheck the score in 5 minutes
• D. Provide no action except to support the infant's spontaneous efforts

Correct answer: B

Rationale: The Apgar score is a method for rapidly evaluating an infant's cardiorespiratory adaptation after birth. The nurse assigns scores in five areas: heart rate, respiratory effort, muscle tone, reflex response, and color, totaling the scores. A score of 8 to 10 requires no action other than supporting the infant's spontaneous efforts and observation. A score of 4 to 7 indicates the need to gently stimulate the infant by rubbing his back while administering oxygen. If the score is 1 to 3, the infant requires resuscitation. Therefore, in this scenario with an Apgar score of 6, the correct action is to gently stimulate the infant by rubbing his back while administering oxygen. Initiating cardiopulmonary resuscitation would be excessive at this point, and rechecking the score in 5 minutes may delay necessary interventions. Providing no action except to support the infant's spontaneous efforts is insufficient for a score of 6, indicating the need for stimulation and oxygen administration.

4. When preparing to listen to a client's breath sounds, what technique should a nurse use?

• A. Ask the client to sit and lean forward slightly, with the arms resting comfortably across the lap.
• B. Listen to the right lung first, then the left lung, moving from top to bottom systematically.
• C. Ask the client to take deep breaths through the mouth.
• D. Use the diaphragm of the stethoscope, holding it firmly against the client's chest.

Correct answer: D

Rationale: When preparing to listen to a client's breath sounds, a nurse should ask the client to sit and lean forward slightly, with the arms resting comfortably across the lap. The client should be instructed to breathe through the mouth a little more deeply than usual but to stop if feeling dizzy. The nurse should use the flat diaphragm end-piece of the stethoscope, holding it firmly on the chest wall. By using the diaphragm, the nurse can listen for at least one full respiration in each location, moving from side to side to compare sounds. This technique ensures a systematic and thorough assessment of lung sounds. Choice A is correct as it includes the proper positioning of the client and specifies the use of the diaphragm of the stethoscope. Choice B is incorrect as both lungs should be auscultated systematically, starting from the top and moving down. Choice C is incorrect as deep breaths, not shallow ones, are recommended for an accurate assessment of breath sounds.

5. When examining the abdomen, a nurse auscultates before palpating and percussing the abdomen. The nurse performs the assessment in this manner for which reason?

• A. It is less painful for the client.
• B. Palpation and percussion can increase peristalsis.
• C. It identifies any potential areas of abdominal tenderness.
• D. It gives the client more time to become comfortable with the examiner.

Correct answer: B

Rationale: When performing an abdominal assessment, the nurse auscultates the abdomen after inspection. Auscultation is done before palpation and percussion because these assessment techniques can increase peristalsis, which would yield a false interpretation of bowel sounds. This sequence helps prevent false interpretations of bowel sounds due to increased peristalsis caused by palpation and percussion. Options A, C, and D provide incorrect reasons for auscultating the abdomen before palpating and percussing it.
